Assessing the Effect of Enzymatic Debridement on the Scar Quality in Partial-Thickness Burns to Deep Dermal Burns of the Hand: A Long-Term Evaluation.

Background and Objectives: Burn surgery on the hands is a difficult procedure due to the complex anatomy and fragility of the area. Enzymatic debridement has been shown to effectively remove burn eschar while minimizing damage to the surrounding tissue and has therefore become a standard procedure in many burn centers worldwide over the past decade. However, surprisingly, our recent literature review showed limited valid data on the long-term scarring after the enzymatic debridement of the hands. Therefore, we decided to present our study on this topic to fill this gap. Materials and Methods: This study analyzed partial-thickness to deep dermal burns on the hands that had undergone enzymatic debridement at least 12 months prior. Objective measures, like flexibility, trans-epidermal water loss, erythema, pigmentation, and microcirculation, were recorded and compared intraindividually to the uninjured skin in the same area of the other hand to assess the regenerative potential of the skin after EDNX. The subjective scar quality was evaluated using the patient and observer scar assessment scale (POSAS), the Vancouver Scar Scale (VSS), and the "Disabilities of the Arm, Shoulder, and Hand" (DASH) questionnaire and compared interindividually to a control group of 15 patients who had received traditional surgical debridement for hand burns of the same depth. Results: Between January 2014 and December 2015, 31 hand burns in 28 male and 3 female patients were treated with enzymatic debridement. After 12 months, the treated wounds showed no significant differences compared to the untreated skin in terms of flexibility, trans-epidermal water loss, pigmentation, and skin surface. However, the treated wounds still exhibited significantly increased blood circulation and erythema compared to the untreated areas. In comparison to the control group who received traditional surgical debridement, scarring was rated as significantly superior. Conclusions: In summary, it can be concluded that the objective skin quality following enzymatic debridement is comparable to that of healthy skin after 12 months and subjectively fares better than that after tangential excision. This confirms the superiority of enzymatic debridement in the treatment of deep dermal burns of the hand and solidifies its position as the gold standard.

Scientific validation of clinical visual scales and Antera 3D™ consistency with derived measurements in the assessment of infantile haemangioma after laser therapy.

BACKGROUND: Laser therapy is a treatment for infantile haemangiomas. The efficacy of laser therapy for red lesions is determined by visual evaluation; however, this assessment is inaccurate and lacks objectivity. OBJECTIVE: To scientifically validate the consistency between pre- and post-treatment visual assessment grades for infantile haemangioma treated with pulsed dye laser (PDL) and the values calculated from images obtained with Antera 3D™. METHODS: This study involved 81 cases of infantile haemangiomas treated with PDL alone from 2012 to 2015 and with Antera 3D™ images of the lesions. Using images obtained before treatment and 4-6 weeks after the last treatment, the lesions were rated using a visual four-step scale. Ratings were categorised as Poor/Fair/Good/Excellent by the degree of improvement in the red colour tone. The red colour ratio was calculated using the haemoglobin distribution in the lesion and surrounding skin, and the improvement difference and improvement rate were then obtained. The correlation between the improvement difference and improvement rate, and visual evaluation was statistically analysed. RESULTS: No serious adverse effects were observed, with an average of 4.3 treatments per patient; 60.1% of the patients achieved Good/Excellent results. There were statistically significant differences in the post-treatment red colour ratio and improvement ratio in each category after visual evaluation classification. The improvement rate and the four visual grades were statistically correlated. CONCLUSION: This study confirmed the scientific validity of visual evaluation and the evaluation criteria calculated from Antera 3D™. This method could objectively determine treatment effectiveness.

A 595 nm pulsed dye laser as an adjuvant intervention for post-comedone extraction erythema and comedone reduction: A randomized, split-face controlled trial.

BACKGROUND: Comedone extraction provides greater satisfaction for acne treatment than conventional treatment alone; however, post-comedone extraction erythema (PCEE) remains a concern for patients. OBJECTIVES: To evaluate the efficacy of pulsed-dye laser (PDL) in PCEE and comedone reduction. METHODS: Mild-to-moderate acne patients were randomly allocated in split-face fashion. Three comedones were extracted on each facial side. On the PDL-treated side, 595-nm PDL was delivered to the entire side with an additional shot on three comedone-extracted sites. Erythema index (EI) and total acne lesion counts (TALC) were evaluated at baseline, week 2 and 4. The comprehensive acne severity scale (CASS) was assessed by three blinded independent pediatric dermatologists. Participant satisfaction surveys were completed at the end of the study. RESULTS: Thirty-five participants (age 12.9-24.2 years) showed no differences in the EI and TALC at baseline on both sides. At weeks 2 and 4, the EI on the PDL-treated side was significantly lower (p < 0.001) with a greater EI reduction (p < 0.001) when compared to the control side regardless of gender and menstruation. There was significantly lower TALC on the PDL-treated side at week 2 (p < 0.001) and week 4 (p = 0.02). No complications were noted with high participant satisfaction reported (median 8; IQR 7-9). PDL remained significantly associated with EI improvements after controlling for gender, menstruation cycle, and examination stress. CONCLUSION: PDL can be an adjunctive intervention for the treatment of PCEE and comedone reduction due to its effectiveness and high participant satisfaction.

Effects of Curcumin on the treatment of oral lichen planus symptoms: a systematic review and meta-analysis study.

BACKGROUND AND OBJECTIVES: Oral lichen planus (OLP) is a relatively common chronic T-cell-mediated disease that can cause significant pain, particularly in its erosive or ulcerative forms. This study aimed to examine the therapeutic impact of curcumin on symptoms of OLP. MATERIALS AND METHODS: This meta-analysis was performed according to the PRISMA guidelines. All related English documents indexed in electronic databases (including PubMed, Web of Science, Scopus, Embase, Wiley, Cochrane, and ProQuest databases [updated to August 15, 2023]) were retrieved. Data were double-extracted into a predefined worksheet, and quality analysis was performed using the Joanna Briggs Institute (JBI) scale. We carried out meta-analyses, and the random effects model was used to estimate the differences in erythema, lesion size, and pain between the curcumin control groups. RESULTS: The search identified 289 studies, of which 10 were found to meet the inclusion criteria. The overall findings of the meta-analysis revealed that curcumin did not have a significant effect on erythema of OLP (standardized mean difference [SMD] = -0.14; 95% CI, -0.68 to 0.40; P = 0.61; I2 = 57.50%), lesion size of OLP (SMD = -0.15; 95% CI, -0.45 to 0.15; P = 0.33; I2 = 28.42%), and pain of OLP (SMD = -0.38; 95% CI, -0.97 to 0.22; P = 0.22; I2 = 86.60%). However, subgroup analysis based on treatment duration indicated that 2-week treatment duration was significantly associated with a reduction in OLP pain (n = 3; SMD = -1.21; 95% CI, -2.19 to -0.23; P = 0.01). CONCLUSIONS: Curcumin had no significant effect on erythema, lesion size, and pain of OLP compared to the control groups. However, subgroup analysis revealed that curcumin was more effective in reducing pain in non-randomized trials and in trials with a treatment duration of 2 weeks.

Adalimumab induced exacerbation of psoriasis in patients with combined pemphigus: A case report.

RATIONALE: Psoriasis is an immune-related disease caused by genetic factors, abnormalities in the immune system and environmental factors, while pemphigus is an autoimmune disease caused by the autoimmune system attacking the skin and mucosal tissues. Herein, we aimed to report a rare case of adalimumab induced exacerbation of psoriasis patients with pemphigus. The rare disease causes considerable challenges for clinical diagnosis and treatment. PATIENT CONCERNS: The patient was a 43-year-old man with intermittent erythema and scaling all over the body for more than 20 years, and blisters and vesicles on the trunk and limbs for 1 month. Half a year ago, the patient had blisters on the limbs, and was diagnosed with deciduous pemphigus in a hospital, and the blisters subsided after being given traditional Chinese medicine orally. Half a month ago, the erythema area was enlarged, and adalimumab 80 mg intramuscular injection was given for 1 time after consultation in the hospital. On the following day, the area of erythema and scales was suddenly enlarged obviously compared with the previous 1, and obvious blisters and vesicles appeared on the limbs, neck, and trunk, which were aggravated progressively and accompanied by obvious itching and pain. DIAGNOSES: The patient was diagnosed with psoriasis in patients with combined pemphigus. INTERVENTION: After combined treatment with methylprednisolone and cyclosporine, the skin lesions have basically recovered. OUTCOMES: The skin lesions have basically healed. Follow up for 6 months without recurrence. LESSONS: Methylprednisolone combined with cyclosporine may be an option in treating patients with psoriasis patients with pemphigus.

Cutaneous nodular polyarteritis presenting as refractory ulcers on both lower extremities: A case report.

BACKGROUND: Cutaneous polyarteritis nodosa (cPAN) is a systemic disease that is limited to the skin. cPAN usually presents with cutaneous reticular cyanotic, erythematous and palpable nodules, and cutaneous ulcers.Research has indicated that the use of hormones and immunosuppressive drugs can delay ulcer healing and associated neuropathy, and also elevate the risk of disease recurrence upon their reduction or withdrawal. Therefore, it is a necessary to find a safe and effective approach that minimize hormone side effects in ulcer treatment. CASE PRESENTATION: The patient, a 48-year-old female of Han Chinese ethnicity, has suffered from recurrent erythema nodosum on both lower limbs for 8 years. The condition was aggravated by skin breakdown over the last 3 months. Despite multiple treatments, the patient's condition did not improve significantly, leading to the exploration of a combined approach of traditional Chinese and Western medicine. Following six months of combined traditional Chinese and Western medicine treatment, t the patient's newborn erythema and ulcers on both lower limbs did not reappear, and the ulcers gradually decreased in size and the erythema disappeared. The patient took the TCM regularly until April 15, 2023, when the ulcers were completely healed. Three months after the patient stopped taking TCM, the ulcers had completely healed with no recurrence, as observed during the follow-up visit on July 14th, 2023. CONCLUSION: Traditional Chinese Medicine Combined with Low-Dose Hormones May Effectively Treat Bilateral Lower Extremity Skin Ulcers Caused by Cutaneous Polyarteritis Nodosa.

Painless photodynamic therapy for facial actinic keratoses: A retrospective cohort study of the post-treatment inflammatory response.

INTRODUCTION: Photodynamic therapy (PDT) is a safe, non-mutagenic, and non-scarring treatment for actinic keratoses (AK). BACKGROUND: 'Painless' photodynamic therapy (p-PDT) is a regimen for AK that employs simultaneous aminolevulinate incubation and blue light illumination. The efficacy of p-PDT resembles that of traditional PDT, but detailed mechanisms of action for p-PDT are not well understood. METHODS: To characterize the inflammatory effects of the p-PDT procedure 48 h following treatment and determine the association of inflammation with precancer burden, we performed a retrospective cohort study of 104 patients with AK of face or scalp treated with p-PDT between 2017 and 2019. Patients self-reported their side effects 48 h following p-PDT and took photographs of their face and scalp. Photographs were edited to define seven anatomic regions, and erythema was scored by four investigators. RESULTS: Ninety-eight patients provided photographs suitable for erythema evaluation. Most patients experienced 2 or more side effects and some pain 48 h post-procedure. Females experienced more pain (p = 0.01) and side effects (p = 0.002) compared to males. AK burden was positively associated with post p-PDT erythema response (p < 0.0001) at all sites, but particularly in the temples (p = 0.002) and supralabial area (p = 0.009). DISCUSSION: This study confirms a strong clinical inflammatory response after p-PDT. Severity of inflammation is positively associated with AK tumor burden, suggesting that post-treatment inflammation may be a pre-requisite for p-PDT efficacy. Interestingly, the results also identify certain gender-related differences in the severity of side effects experienced by patients post-PDT.

Photobiomodulation for melasma treatment: Integrative review and state of the art.

PURPOSE: Photobiomodulation therapy (PBM) is a versatile technique for treating skin diseases. Melasma, a chronic hyperpigmentation condition, has recently been associated with vascular features and dermal photoaging and poses significant management challenges. We review the recent literature on melasma etiology and the evidence supporting PBM as a therapeutic modality for melasma treatment. METHODS: We conducted a comprehensive literature search in three different databases from May to August 2023, focusing on studies published in the past 10 years. The inclusion criteria comprised full-text studies investigating low-power lasers and/or light-emitting diodes (LEDs) in in vitro or in vivo models, as well as clinical trials. We excluded studies discussing alternative melasma therapies or lacking experimental data. We identified additional studies by searching the reference lists of the selected articles. RESULTS: We identified nine relevant studies. Clinical studies, in agreement with in vitro experiments and animal models, suggest that PBM effectively reduces melasma-associated hyperpigmentation. Specific wavelengths (red: 630 nm; amber: 585 and 590 nm; infrared: 830 and 850 nm) at radiant exposures between 1 and 20 J/cm2 exert modulatory effects on tyrosinase activity, gene expression, and protein synthesis of melanocytic pathway components, and thus significantly reduce the melanin content. Additionally, PBM is effective in improving the dermal structure and reducing erythema and neovascularization, features recently identified as pathological components of melasma. CONCLUSION: PBM emerges as a promising, contemporary, and non-invasive procedure for treating melasma. Beyond its role in inhibiting melanogenesis, PBM shows potential in reducing erythema and vascularization and improving dermal conditions. However, robust and well-designed clinical trials are needed to determine optimal light parameters and to evaluate the effects of PBM on melasma thoroughly.

The combined treatment of gold nanoparticles associated with photobiomodulation accelerate the healing of dermonecrotic lesion.

Introduction: The search for fast and efficient treatment for dermonecrotic lesions caused by the venom of the spider from the Loxosceles simillis, is a demand in health. Prednisolone is one of the most used drugs, however it has side effects. In this context, addictionally gold nanoparticles (GNPs) have anti-inflammatory, antioxidant, and antibacterial properties. The use of photobiomodulation has show to be efficient in the process of tissue repair. Therefore, the purpose of this study was to investigate the anti-inflammatory effect of photobiomodulation and GNPs associated or not with a low concentration of prednisolone in animal models of dermonecrotic lesion.Methodology: For this, rabbits with venon-induced dermonecrotic lesion were subjected to topical treatment with prednisolone + laser or GNPs + laser or Pred-GNPs + laser. The area of edema, necrosis and erythema were measured. On the last day of treatment, the animals were euthanized to remove the organs for histopathological and biochemical analysis.Results: All treatments combinations were effective in promoting the reduction of necrotic tissue and erythema.Conclusion: With this results, we suggest that the use of laser and nanoparticles, associated or not with prednisolone, should be considered for the treatment of dermonecrotic injury.

Narrow-Band Intense Pulsed Light as Treatment for Erythematotelangiectatic Rosacea: A Retrospective Study.

BACKGROUND: Erythematotelangiectatic rosacea can be successfully treated using various laser and light-based devices. However, the use of narrow-band intense pulsed light for the treatment of erythematotelangiectatic rosacea has not been investigated in detail. This retrospective study aimed to analyze the clinical efficacy of narrow-band intense pulsed light (500-600 nm) for the treatment of erythematotelangiectatic rosacea among Chinese individuals.  Methods: Patients with erythematotelangiectatic rosacea who had completed 3 sessions of treatment with narrow-band intense pulsed light and follow-up from July 2016 to December 2018 were retrospectively evaluated. Clinical improvement was assessed by 2 blinded dermatologists based on photographs obtained at each follow-up visit using the clinician erythema assessment scale and 5-grade scale. RESULTS: Forty-five patients with erythematotelangiectatic rosacea treated with narrow-band intense pulsed light were included in this study. The effectiveness and excellent rates after 3 treatment sessions were 68.9% and 35.6%, respectively. An average of 2 treatment sessions was required among patients who achieved good or excellent clearance of erythema and telangiectasia. Except for transient erythema and edema, no severe adverse effects were observed. CONCLUSIONS: Narrow-band intense pulsed light is a safe and effective treatment for erythematotelangiectatic rosacea. Even with a small number of treatment sessions, narrow-band intense pulsed light can deliver a significant therapeutic effect, which may be applicable in clinical practice.

Veterinary Dental Photobiomodulation: Assessing Post-Treatment Gingival Inflammation in Canines.

Objective: This research aims to determine the effect photobiomodulation treatment has on oral inflammation after routine dental prophylaxis in canines. Background: Photobiomodulation therapy after dental procedures has been documented to reduce inflammation in human and animal models. Methods: Canines were randomly assigned into three groups: control group (CG; n = 15), left side treated group (LTG; n = 15), and right side treated group (RTG; n = 15). The canines in the treatment groups received four points of irradiation [GaAlInP-650 nm, continuous wave (CW), 0.1 W, 0.2 W/cm2, 100 sec, 10 J, 20 J/cm2]. The gingiva was evaluated by a veterinary investigator blinded to the treatment groups for erythema and edema on the day following treatment. Student's t-test and Student's paired t-test were used for data analysis. Results: Reductions in composite inflammation (p = 0.008) and erythema (p = 0.030) were observed in the LTG relative to the CG at the location of the left dental arcade. Reductions in composite inflammation (p = 0.025) and erythema (p = 0.013) were also observed in the combined treated arcades of the LTG and RTG when compared to the CG. Conclusions: The results indicate that the canines who received a single photobiomodulation treatment on the left dental arcade demonstrated a decrease in inflammation and erythema.

Dietary habits in Japanese patients with bullous pemphigoid: low intake of retinol.

BACKGROUND: Bullous pemphigoid (BP) is an autoimmune subepidermal blistering disease. Dietary habits may modulate the pathogenesis of BP. OBJECTIVES: We evaluated dietary habits in Japanese patients with BP and compared their results to those of age- and sex-matched healthy controls. We also examined the relationship between dietary habits versus IgG anti-BP180NC16A antibody or parameters of BP disease area index (BPDAI); cutaneous blisters/erosions, cutaneous urticaria/erythema, and mucosal blisters/erosions. MATERIALS & METHODS: Dietary habits were assessed by the validated, Brief-type self-administered Diet History Questionnaire. Severity of disease was assessed with BPDAI. RESULTS: Patients with BP showed a lower intake of retinol (vitamin A1) and beverages, and a higher intake of seasoning/spices, compared to controls. The bivariate and multivariable logistic regression analysis showed that BP was associated with a low intake of retinol and beverages. There were no significant correlations between IgG anti-BP180NC16A antibody levels and intake of nutrients/foods. The BPDAI score for cutaneous blisters/erosions significantly positively correlated with intake of carbohydrate and negatively with intake of retinol, vitamin A, animal fat, cholesterol, phosphorus, and vitamin B2. The BPDAI score for cutaneous urticaria/erythema significantly negatively correlated with intake of vitamin A. BP patients with mucosal blisters/erosions had a higher intake of cholesterol, n-6 polyunsaturated fatty acid, and eggs, and lower intake of seasoning/spices, compared to patients without BP. CONCLUSION: The supplementation of vitamin A might have prophylactic and/or therapeutic effects on BP.

Involvement of silver and palladium with red peanuts skin extract for cotton functionalization.

A systematic study is currently demonstrated approach for approving the superior role of silver and palladium metallic particles in acting the role of mordant with acquiring the dyed cotton fabrics excellence in color fastness with additional functions of antimicrobial potentiality and UV-protection action. Whereas, samples were dyed with extract of red peanuts skin as natural textile colorant (RPN dye). The represented data revealed that, in absence of mordant, the samples treated with metal precursors prior to dyeing were exhibited with the excellent color strength, color fastness, antimicrobial action and UV-protection action. Color fastness (washing, rubbing and light fastness) was estimated to be in the range of very good-excellent. Sample pretreated with silver salt and dyed in the absence of mordant was graded with excellent UV-protection action (UPF 31.5, UVB T% 2.6% and UVB blocking percent 97.4%). Antimicrobial potency against E. coli, S. aureus and Candida albicans through inhibition zone and the reduction percent was approved to be in the range of excellence (93.01-99.51%) for the samples dyed in absence of mordant and pretreated with either silver or palladium precursors.

Could red and near-infrared emitting fabric technology improve the severity of psoriasis, polymorphous light eruption, and alopecia areata?

AIM: Low-level light therapy (LLLT) may offer an adjunctive therapeutic tool for inflammatory skin conditions. This pilot study assessed the efficacy of a red/near-infrared (NIR)-emitting fabric for psoriasis, polymorphous light eruption (PMLE), and alopecia areata (AA). METHODS: Fourteen patients (five with psoriasis, five with PMLE, and four with AA) were instructed to wear a red/NIR-emitting (Lumiton®) garment during the 12-week study. Efficacy was assessed subjectively by patient-reported improvement and objectively by the redness, thickness, and scale of elbow psoriasis plaques, the frequency of PMLE flares, and the Severity of Alopecia Tool (SALT) score. RESULTS: Three patients with psoriasis completed the study while two self-discontinued. The three patients who completed the study noted improvement and two had improvements in lesion redness, thickness, or scale, while one was clinically stable. Three patients with PMLE completed the study, and none had a disease flare during the study period. Three patients with AA completed the study: two reported disease improvement and all three had an improved SALT score. CONCLUSION: Use of a wellness apparel that emits red and NIR light may be associated with improved disease severity in patients with mild elbow psoriasis, PMLE, and limited AA. Limitations of this study include continuation on topical, intralesional, or systemic medications and small sample size.

Nutraceutical combination ameliorates imiquimod-induced psoriasis in mice.

Psoriasis is a chronic inflammatory skin disease that affects both localized and systemic regions of the body. This condition is characterized by the hyperproliferation of keratinocytes, resulting in skin thickening, scaling, and erythema. The severity of psoriasis depends on the extent of skin involvement, the location of the infection, and the symptoms that the person exhibits. While no cure exists, conventional therapies such as topical and systemic drugs are generally used to manage the exacerbation of symptoms. However, chronic use and overdose can lead to other severe adverse effects. Therefore, scientists and researchers are exploring potential nutraceuticals that can be considered as an alternative source of management for psoriasis. Current research aims to use different combinations of natural compounds like cannabidiol, myo-inositol, eicosapentaenoic acid, and krill oil to study the effect of these compounds in the prevention and treatment of psoriasis in the imiquimod (IMQ)-induced psoriatic mice model. The Psoriasis Area Severity Index (PASI) scoring system is used to analyze skin thickness, scales, and erythema. The results indicate that the krill oil combined with the cannabidiol and myo-inositol shows better results than other nutraceutical combinations. In the future, the natural products of krill oil can be combined with cannabidiol and myo-inositol to create an improved alternative to existing steroidal and nonsteroidal anti-inflammatory drugs for psoriasis treatment.

A new 532 nm, variable-pulse-structure, dual-wavelength, KTP laser incorporating cryogen spray cooling, effectively treats rosacea.

BACKGROUND: A new dual-wavelength, high-energy, solid-state laser incorporating both 532 and 1064 nm wavelengths was developed with cryogen spray cooling and the unique ability to deliver three types of pulse structures including single pulses of a specific pulse-duration or pulses composed of a train of subpulses in the millisecond or microsecond domain with an intervening delay over the selected pulse-duration. We investigate the efficacy of this laser using all three pulse structures and the 532 nm wavelength for treating rosacea. METHODS: Twenty-one subjects were enrolled in this IRB-approved study. A total of up to three treatments were administered at monthly intervals. Each treatment consisted of a first pass tracing linear vessels with a 40 ms pulse-duration immediately followed by a second pass using a 5 ms pulse, using all three available pulse structures. Assessment of cross-polarized digital images by blinded physician observers compared baseline and 3-month follow-up images. RESULTS: Blinded observers correctly identified the posttreatment images 89% of the time, in 17 of 19 subjects completing the study, with an average overall improvement rating of 39% after only three treatments. Side effects were limited to short-term erythema and edema. CONCLUSION: This study demonstrates that this new, variable-pulse-structure, dual wavelength, solid state, KTP laser with dynamic cooling is a safe and effective for treating rosacea.

Efficacy and safety of intense pulsed light for the treatment of facial erythema: a systematic review and meta-analysis.

INTRODUCTION: Facial erythema can be seen in many patients. Despite various clinical trials exploring the effect of intense pulsed light (IPL) in treating facial erythema, comprehensive evidence about the specific outcomes remains lacking. EVIDENCE ACQUISITION: We searched published studies in the Web of Science, PubMed, Embase, and Cochrane Library databases based on established inclusion criteria. We calculated odds ratios (OR) to evaluate the effectiveness of IPL in patients with facial erythema. We used Review Manager 5.4.1 software for statistical data analyses with a 95% confidence interval (CI). EVIDENCE SYNTHESIS: This review includes seven studies with 219 patients, of which five compared the efficacy of IPL with pulsed dye laser (PDL). IPL significantly improved facial erythema compared to no treatment (OR=56.64, 95% CI: 22.70-141.33; P<0.00001). However, there was no significant difference between IPL and PDL treatment (OR=1.00, 95% CI: 0.31-3.22; P=1.00). Moreover, there was no significant difference in patients with a >50% reduction in telangiectasias between IPL and PDL treatment (OR=1.00, 95% CI: 0.39-2.56; P=1.00). Furthermore, IPL therapy had no apparent adverse effects for most people besides transitory edema and erythema. CONCLUSIONS: Our meta-analysis indicated that IPL could effectively and safely improve facial erythema with similar efficacy to PDL. Based on its comprehensive function, light side effects, and long curative effect, IPL appears to be a good alternative for treating facial erythema. However, further prospective and high-quality studies are required.

Clinical and histological features and treatment outcomes of patients with Morbihan disease: a systematic review.

Morbihan disease (MD) is considered a rare complication of rosacea, which is difficult to diagnose and challenging to treat. Here, we performed a systematic review of available case reports and case series to summarize key clinical and pathologic features of and successful treatment regimens for MD. We conducted a search of the PubMed/MEDLINE, EMBASE, and Cochrane electronic databases from their inception to the date of search on March 6, 2023. We found that MD affects patients in the fifth decade of life on average, more commonly reported in male than female (69% vs 31%). Clinically, MD affects the eyelids, cheeks, and forehead most commonly, presenting as non-pitting, erythematous edema or an edematous plaque. On biopsy, the pathologic features, such as dermal edema, sebaceous hyperplasia, perivascular and periadnexal inflammatory infiltrate, and granulomatous reaction, are frequently reported. Out of 55 patients who were able to achieve complete response without recurrence, 35% of patients were treated with isotretinoin and 22% were treated with tetracycline antibiotics with a daily dosage range of 20-80 mg and 40-200 mg, respectively. Out of those 55 patients, 22% and 7% were treated successfully with surgical intervention and intralesional injection of steroids, respectively. Additionally, lymphatic drainage has been shown to be an effective adjunctive therapeutic tool. More studies are necessary to understand the disease mechanism to improve the diagnosis of and develop evidence-based therapies for MD.

Evaluating the effect of tranexamic acid as mesotherapy on persistent post-acne erythema: A before and after study.

BACKGROUND: Acne vulgaris is a common skin disease that is more common in young population and it can be associated with some sequels after resolving the lesions. Post-inflammatory erythema is one of these complications that can be disturbing for patients and does not have any definite treatment. This study was aimed to evaluate the efficacy and safety of tranexamic acid (TA) as mesotherapy in treatment of post-acne erythema (PAE) treatment. METHOD: This clinical trial study was performed in the dermatology clinic on 17 patients with persistent PAE (3 months after acne recovery). Two sessions of treatment were performed by a physician with 2-week intervals; TA was injected as mesotherapy into the right side of each patient's face as the case group, while the opposite side was used as the control group. A Visioface device was used to compare before and after treatment photographs of each side of the face in color mode with quantitative measures such as lesions count, area, and area percent. RESULTS: Finally, 15 patients completed treatment sessions. There were statistically significant differences in right side lesions before and after treatment with p-values of 0.047, 0.002, and 0.035 for count, area, and area percent, respectively. There was no significant difference before and after treatment in terms of count, area. and area-percent on the left side. CONCLUSION: According to the results of this study, TA injection as mesotherapy for resolving PAE can be effective. However, due to small sample size, further studies are needed.
